The IESG has received a request from the Secure Shell Maintenance WG (sshm)
to consider the following document: - 'PQ/T Hybrid Key Exchange with ML-KEM
in SSH'
  <draft-ietf-sshm-mlkem-hybrid-kex-05.txt> as Informational RFC

The IESG plans to make a decision in the next few weeks, and solicits final
comments on this action. Please send substantive comments to the
last-call@ietf.org mailing lists by 2026-01-01. Exceptionally, comments may
be sent to iesg@ietf.org instead. In either case, please retain the beginning
of the Subject line to allow automated sorting.

Abstract


   This document defines Post-Quantum Traditional (PQ/T) Hybrid key
   exchange methods based on the quantum-resistant the Module-Lattice-
   Based Key-Encapsulation Mechanism (ML-KEM) standard and traditional
   Elliptic-curve Diffie–Hellman (ECDH) key exchange schemes.  These
   methods are defined for use in the SSH Transport Layer Protocol.
